It means God isn't distant, but is so close as to be one of us.
It means a perfect human being is directing the universe.
It means that atheism may be an honest and respectable intellectual position, but also one that happens to be untrue.
It means that everything I see is significant because God himself entered his created universe.
It means that humanity will always live.
It means that I can live!
It means God united to us forever.
Merry Christmas, everyone!
